This 'Kidspace' feature is a good primer on geological mapping, and offers several fun projects to do with your kids.
"Geologists use photos, sound waves, drilling -- even earthquakes to find out what lies beneath your feet.
...Geologic maps can help you find your way across the landscape, but they have many other important uses, too.

They help builders locate safe, secure sites for new buildings and guide engineers planning the route of a new highway.
...You can make a seismometer to measure movements in your home..."
